> So unless you burn cash in a fire or counterfeit money, the only entity that can create and destroy money is the Federal Reserve.
I think this is generally false as a premise depending on your definition of “money”. If your definition of money is equivalent to US dollars then I guess this could be interpreted as correct, but other countries have “money” that isn’t issued by the Federal Reserve (the Federal Reserve being what we refer to as the US banking system)
> The price of AMD stock can go up and down ("value") but the total dollars created or destroyed is always zero. Same is true with BTC.
I don’t understand why you’re comparing the “value” of a stock or bitcoin with the “amount” of dollars. A fair comparison would involve the value of the US dollar, which is subject to change (take a look at the Forex market to see people capitalizing on that every day).
> The miners spend money burning energy which removes "value" from the economy as a whole
“Burning energy” is not removing value, it’s providing value by means of strengthening a proof of work blockchain. Whether that’s worth something to you is irrelevant to it being valuable to others.
> If I give you a ton of coal you can burn that for heat. But that removes the coal permanently from the world. OTOH, if I want to make a cryptocurrency with 10^86 coins and if I do that a billion times over, well, I have a limitless supply of cryptocurrency.
It seems like you’re saying scarcity implies value here. If that is what you’re implying, this arguments starts to take the form of a “straw man”. Bitcoin is not unlimited. Part of Bitcoin’s whole appeal is that there is a limited quantity of it to go around. Grouping Bitcoin with any other random cryptocurrency without that limitation will make any argument related to it a moot point.
> You might say that's exactly what credit card transactions are, (which is not incorrect) but the burn rate of Visa per transaction is much less than BTC.
I will agree that the amount of electricity to process a transaction on the Visa network is a lot lower than the energy required to run the Bitcoin infrastructure, but that energy just happens to be the price needed to pay for a decentralized proof of work blockchain. Even if you subjectively don’t believe Bitcoin is worth the value that’s spent to maintain its infrastructure, other people do and that’s reflected in the current economy.
